In this lab, we will learn about the different ways to initialize a vector in C++. We will cover the following methods:
C++
Storing and Displaying Employee Information
Storing and Displaying Employee Information
In this lab, we will create a C++ program that stores and displays employee information using structures. This program will help us understand how structures can be used to store data with different data types. We will use an array of structures to store multiple records of employee information and then display it in a formatted manner.
C++
Crafting C++ Diamond Pattern
Crafting C++ Diamond Pattern
In this lab, we will learn how to write a C++ program to print a diamond pattern using asterisks (\*). We will create this program step by step.
C++
Find Maximum Number in Three Given Numbers
Find Maximum Number in Three Given Numbers
In this lab, we will write a C++ program that will take three numbers as input from the user and find the maximum among them using if/else statements.
C++
Flip Pattern Half Pyramid in C++
Flip Pattern Half Pyramid in C++
In this lab, we will be creating a program in C++ to print a flip pattern of a half pyramid using * symbol. We will be printing the pattern in such a way that the number of stars in each row starts with the maximum number and then decreases by one in each consecutive row.
C++
Determine Prime Number in C++
Determine Prime Number in C++
In this lab, you will learn how to write a C++ program to check whether a given number is a prime number or not. A prime number is a number that is only divisible by 1 and itself. It is an important concept in number theory and has many important applications in cryptography.
C++
Compute Sum of Squares in C++
Compute Sum of Squares in C++
In this lab, we will learn how to write a C++ program to find the sum of the series 1^2 + 3^2 + 5^2 + ... + n^2 using two different approaches. We will guide you through step-by-step to help you understand the process.
C++
Finding Average of N User Input Numbers
Finding Average of N User Input Numbers
In this lab, we will learn how to calculate the average of n numbers entered by the user without making use of an array in C++. We will go through the code line by line and understand how it works.
C++
File Content Copying in C++
File Content Copying in C++
In this lab, we will learn how to copy contents of one file to another using file handling in C++ language.
C++
Counting Characters in a File Using C++
Counting Characters in a File Using C++
In this lab, we will learn how to count the occurrence of a character in a file using C++ programming. We will create a C++ program that reads a file and counts the number of times a particular character occurs in the file.
C++
Perform Arithmetic Operations Using Functions
Perform Arithmetic Operations Using Functions
In this lab, you will learn how to write a C++ program to perform arithmetic operations using functions. Specifically, you will create separate functions for addition, subtraction, multiplication, and division of two numbers, inputted by the user.
